HuffPostTech is having trouble accessing Gmail as well--we're seeing the error message, "We're sorry, but your Gmail account is temporarily unavailable. We apologize for the inconvenience and suggest trying again in a few minutes."

As of 4:00PM ET, Google has no mention of a Gmail outage on the Google App Status Dashboard, where you can check on Gmail's status. You can also get updates on Gmail via the live Twitter feed below.
